PARASITIC MODE

borer: larva living internally, almost no outwards signsdown: 0.5-2 mm high fungal downfilm: very thin cover of fungal tussuegall: swelling and/or malformationgrazer: feeding at the outside of the plantleaf spot discoloured, often ± necrotic, generally not galled, sign of a fungus infectionminer-borer: larve initially makes a mine, lives as a borer laterpustule: plug of fungal tissue, generally brown-black and < 2 mmstripe: longitudinal line of fungal tissue in a grass leafvagrant: (aphids, mites) living freely on the plant, at higher densitiy causing malformations.

IMPORTANT

The host plant spectre of a parasite is rarely known exhaustively;
this applies in particular at the species level. It is advisable therefore to
check at least also the list of all parasites of this genus.
